<p>One of the seniors who conducted a session at a Caltech summer visiting day was a math/CS major. He seemed pretty happy, but maybe he’s the exception.</p>
<p>Math and CS are very compatible as a double major. However, Caltech is obviously intense and I’m not sure how much extra work a double major would be. Definitely don’t do it just to put it on your resume because it’s not worth it in that regard.</p>
